Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-000CA4 is the active equivalent for the obsolete MX6SWT-H1-R250-000DA4. Selection of the substitute requires circuit redesign due to fundamental electrical differences:

Voltage and Current Architecture: The main part operates at 20V with 60mA test current, while the substitute operates at 3.3V with 300mA test current. These are distinct electrical operating points requiring separate power supply and current-limiting designs.

Optical Performance: Both parts deliver comparable luminous flux (111 lm vs. 104 lm) and maintain identical color temperature (4000K) and CRI (80). The substitute achieves higher efficiency at 105 lm/W versus 93 lm/W.

Mechanical and Thermal Compatibility: Both parts share identical physical dimensions (5.00mm × 5.00mm), seated height (1.48mm), and thermal resistance (5°C/W), enabling direct PCB footprint compatibility.

Compliance and Availability: The substitute is active production status with RoHS compliance certification and Tape & Reel packaging, supporting high-volume manufacturing. The main part is obsolete with no ongoing supply.

Package Variant: The substitute features an exposed pad variant of the Gull Wing package, which may provide improved thermal performance in applications requiring enhanced heat dissipation.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000CA4 be used as a direct drop-in replacement for the MX6SWT-H1-R250-000DA4?

A: No. While both parts share identical physical dimensions and thermal characteristics, they operate at fundamentally different voltages (20V vs. 3.3V) and currents (60mA vs. 300mA). Circuit redesign is required, including modifications to power supply voltage and current-limiting components.

Q: What are the key parameters that define substitution eligibility between these parts?

A: Substitution is based on matching color temperature (4000K), CRI (80), viewing angle (120°), package type (2-SMD Gull Wing), physical dimensions (5.00mm × 5.00mm), and thermal characteristics (5°C/W). Electrical parameters (voltage and current) are design-specific and do not prevent substitution when circuit modifications are implemented.

Q: Are there packaging considerations when switching to the MX6AWT-H1-R250-000CA4?

A: Yes. The main part is supplied loose, while the substitute is supplied in Tape & Reel (TR) format. The substitute also features an exposed pad variant, which may require PCB layout adjustments for optimal thermal performance.

Q: Does the substitute meet current compliance standards?

A: The MX6AWT-H1-R250-000CA4 is RoHS Compliant and REACH Unaffected. The main part does not specify RoHS status. Both parts maintain MSL 2A (4 Weeks) moisture sensitivity classification.

Q: What is the optical performance difference between these parts?

A: The main part delivers 111 lumens at 60mA (93 lm/W), while the substitute delivers 104 lumens at 300mA (105 lm/W). Both maintain 4000K color temperature and 80 CRI. The substitute achieves higher efficiency per watt.
